A system for producing at least one three-dimensional element on a visible face of an external part element of a timepiece implementing this process, the system including a mould formed by the reversible assembly of a first part and a second part configured to receive a support plate of the external part element, the mould including at least one cavity formed by associating the first part including at least one impression with the visible face of the external part element, each cavity helping produce a blank of the three-dimensional element from an over-moulding by injecting injectable material onto the visible face, and a device for applying a coating onto the blank over-moulded on the visible face of the external part element helping finalise this blank of the three-dimensional element.

The invention relates to a process for the production of a part provided with an external element comprising the following steps: provide an electrically conductive substrate having an upper surface and a pattern forming a recess in said upper surface deposit an electrically insulating layer into the pattern so that the insulating layer extends as far as the upper surface deposit a metal layer onto the upper surface of the substrate by galvanic growth so that at the end of this step the metal layer partly rests on the insulating layer dissolve the insulating layer cover an assembly comprising the substrate and the metal layer with a mass of a base material of the part, wherein the mass forms an imprint of the assembly separate the mass and the metal layer from the substrate, wherein the mass then exhibits an external element with a shape corresponding to the imprint of the pattern.

The invention relates to a process for the production of a part provided with an external element, wherein the process comprises the following steps: provide an electrically conductive substrate having an upper surface and a raised pattern on said upper surface, wherein the pattern has an crest deposit an electrically insulating layer onto the upper surface of the substrate around the pattern to a thickness less than or equal to the distance between the crest and the upper surface deposit a metal layer onto the crest of the pattern by galvanic growth so that at the end of this step the metal layer partly rests on the insulating layer dissolve the insulating layer cover an assembly comprising the substrate and the metal layer with a mass of a base material of the part, wherein the mass forms an imprint of the assembly separate the mass and the metal layer from the substrate, wherein the mass then exhibits an external element formed by a recess, the shape of which corresponds to the imprint of the pattern and the base of which interfaces with the metal layer.

A design generation method for a watch part includes the steps of: by an output terminal, transmitting, to a server, watch model information selected by a user and event data including at least a date/time entered by the user; by the server, generating, based on the model information received by the server, model data being component information of the watch part; by the server, generating, based on the event data received by the server, unique data and feature data that are a design element of the watch part; by the server, transmitting, to the output terminal, the model data, the unique data, and the feature data; and by the output terminal, displaying the model data, the unique data, and the feature data on a display unit of the output terminal.

A timepiece includes a dial plate, and a solar battery which is disposed on a rear side of the dial plate. The dial plate is provided with grooves or ridges. The grooves or the ridges have portions where inclination angles with regard to a normal line of the dial plate are different, and due to this, light which is transmitted through the dial plate is incident from a plurality of directions with angles which are different with regard to the solar battery.
